| titleOfInvention | Method of determining the alkali metal hydroxide concentration in an aqua-ammonia-chromate solution for use in an absorption refrigeration system |
| abstract | A method of determining the sodium hydroxide concentration in an aqua-ammonia-chromate absorption solution comprising adding formaldehyde to the solution to react with the ammonia in solution, and then adding a quantity of phenolphthalein indicator and titrating the sodium hydroxide with an acid. The formaldehyde removes the ammonium ions from the solution, and the amount of acid required to neutralize the absorption solution indicates the amount of sodium hydroxide therein. |
